The descriptor descriptor describes the number of interface provided by the configuration.Each interfacemay operate independently.For example,an ISDN device might be configured with two interface,each prviding64KB/s bi-directional channels that have separate data sources or sinks on the host.Another configuration mightpresent the ISDN device as a single interface,bonding the two channels into one 128KB/s bi-directional channels.	When the host requests the configuration descriptor,all related interface and endpoint descriptors arereturn.	A USB device has one or more configuration descriptors.Each configuration has one or more interface and eachinterface has zero or more endpoints.An endpoint is not shared among interfaces whthin a single configurationunless the endpoint is used by alternate settings of the same interface.Endpoints may be shared among interfacethat are part of different configuration.Following shows the standard
